G-protein-coupled receptors (GPCRs) play a pivotal role in various physiological processes and are critical to modern medicine’s landscape. It is estimated that a significant portion of marketed pharmaceuticals engages with GPCRs, underscoring their importance as therapeutic targets for numerous diseases.

The Importance of High-Throughput GPCR Assays

High-throughput GPCR assays are essential in the early phases of drug discovery, facilitating the efficient screening of extensive compound libraries to unearth potential drug candidates. By relying on G-protein-mediated second messengers, these assays prove their utility in functional assessment. Recent advancements have allowed researchers to explore G-protein-independent pathways, enhancing the understanding of GPCR signaling and aiding in discerning the functional selectivity of pharmacological agents.
